Upgraded OpenSSH packages are available for Slackware 8.1, 9.0 and

OpenSSH upgrade to the new OpenSSH package immediately.

   (http://www.openssh.com/txt/buffer.adv):
      "All versions of OpenSSH's sshd prior to 3.7 contain a buffer
       management error.  It is uncertain whether this error is
       potentially exploitable, however, we prefer to see bugs
       fixed proactively."
